BLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 574,432, dated January5, 1897.

Application filed March 2l, 1896.

To @ZZ whom, it may concern/.-

Beit known that I, ELIAS A. JUKEs, asub- ;,iect of the Queen of GreatBritain, residing at St. Catharines, in the Province of Ontario,Dominion of Canada, have invented certain new and useful Improvements inNon-Refillable Vessels; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe letters of reference marked thereon.

This invention relates to improvements in vessels for containingliquids, and has for its object to provide a structure which when itisonce iilled and the liquid emptied or partially emptied therefrom cannotbe again filled without destroying the structure.

In the accompanying drawings, which represent one embodiment of myinvention, Figure 1 is a vertical section taken through the top of avessel'or bottle embodying my invention. Fig. 2 is a detail sideelevation of the valve-block. Fig. 3 is a similar side elevation ofaretainer-block. Fig. 4 illustrates the valve itself. Fig. 5 shows avalve-block having the passages therethrough in the form of open cuts,and Fig. 6 is a detail of the lock for holding the filling-cap in placeafter the vessel is first illed.

Like letters of reference in the several iigures indicate the sameparts.

I have shown the invention applied to a vessel having the configurationof an ordinary bottle A, within the neck of which an annular shoulderBis formed havinga flat upper surface, upon which shoulder the bottom ofa valve-block C seats, preferably leaving an inwardly-projecting portionof the shoulder to constitute a seat upon which a light glass valve Dcomes to rest to check any inward flow of liquid into the bottle. AThisvalve D works within a chamber in the valveblock C, said chamber havinga conical or dome-like top c and containing a spherical valve pusher orball E, adapted to hold said valve to its seat at all times, save whenthe neck of the bottle is tilted down to such a sharp angle as toprevent the entry of liquid therein'or the escape of air from thebottle. This result, it will be seen, is due to the fact Serial No.584,220. (No model.)

that the ball, which is of relatively heavy material, will, when thebottle is turned on its side, run down theinclined sides of the dome cand push the valve before it, but when the bottle is turned upside downthe ball or pusher will roll into said domed top of the chamber,allowing the valve to unseat and the liquid or contents of the bottle toflow out.

The orifices for the escape of the liquid from. the chamber within thevalve-block are formed at the lower edge of the valve-block, as shown atF, preferably below the top of the valve itself and in such relation tothe valve as to be almost if not entirely closed thereby when the valveis seated, the result of which arrangement is that the valve cannot bereached by an instrument or wire and held away from its seat, and,whatis of greater importance, the valve cannot be readily unseated byapplying suction to the mouth of the bottle, andso filling the bottle byalternate suction and pressure cannot be accomplished. An annularenlargement Gis formed around the top of the valve-block, through whichsmall apertures g or slots g', Fig. 5, are formed for the escape of thecontents of the bottle when the valve is unseated.

To hold the valve-block in place and to further insure against allpossibility of an instrument being inserted to unseat the valve andallow the bottle to be filled the second time, I provide a retainerwhich when once inserted in the neck of the bottle above the blockcannot be withdrawn, and in the preferred construction this retainerconsists of two semicylindrical blocks H, pivoting together at a centralpoint and held against independent movement by a rib and recess h. Atthe lower end these blocks H are provided with flanges I, adapted totake into an annular recess i in the neck of the bottle, immediatelyabove the valve-block, and after having been inserted the cylindricalshape, together with the spring or expander K, of asbestos or someelastic material, preferably such as will not be affected by acids, willprevent the withdrawal of the block. f

The expander K may be seated between the lower ends of the blocks, asshown at Fig. 1, or heldin any suitable or preferred manner. Passages Lfor the escape of liquid are formed IOO through the retainer, usually onthe exterior or external surface thereof, and are preferably arrangedspirally thereon, as shown in Fig.

The top of the retainer is preferably made conical and is suilicientlyfar below the mouth of the bottle to permit of the insertion of anordinary cork, such as M, to prevent the escape of the liquid from thebottle.

The pusher or ball may be covered with glass to prevent the action ofacids thereon, and in order that the retainer may be inserted readilythe mouth of the vessel above said retainer is preferably ilared outwardslightly, as will be readily understood from an inspection of Fig. l.

For convenience in filling the bottle in the iirst instance, after theabove-described appliances have been put in place, I preferably providea secondary or lling orifice N, having a screw-threaded nipple n, uponwhich a cap O, provided with a cork packing 0, is adapted to be placed,and when seated held in position by a spring-lock, such, for instance,as a curved spring-wire P, Fig. G, having its ends bent in oppositedirections and adapted to take into apertures p, formed in the cap andbody of the bottle, respectively. lVhen the bottle is filled throughthis aperture and the cap seated, it will be seen that the cap cannot beagain removed without destroying the integrity of the vessel or capitself. It is not essential that this filling-oriiice be employed, asthe bottle may be filled before the check-valve is put in place.

The appliance, it will be seen, forms a most eiectual check against theentry of liquid into the bottle, while permitting of a free escape, theglass valve seating against the glass shoulder or seat in thebottle-neck forming, when wet, a most effectual seal, and inasmuch as itis held in its sealed or seated position by the pusher or ball until theneck of the bottle is tilted below the horizontal position, it isobvious that no liquid can be flowed into the vessel, and by thearrangement of the exit-ports F it is impossible to force liquid in thevessel by alternate suction and pressure.

Having thus described my invention, what l claim as new isl.. Thecombination With a vessel having an inwardly-projecting annular seat orshoulder and having a valve-block resting thereon, having the annularenlargements at top and bottom entirely filling the exit-aperture, andhaving an internal chamber with a domed or conical top and lateralapertures leading from said chamber above the bottom enlargement, of avalve working in said chamber and seating on the annular shoulder of thevessel, and bridging the lateral apertures in the block, a sphericalpusher located in the chamber above the valve and a retainer for holdingsaid valve in place consisting of semieylindrical sections pivotedtogether and having projections at the lower end for coopera-ting withrecesses in the walls of the vessel, substantially as described.

2. The combination with the vessel and the valve located in theexit-aperture thereof of the retainer for holding said valve in placeconsisting of the two semicylindrical sections pivoted together andhaving the projections at the lower end coperatiug with recesses in thewalls of the vessel said sections being respectively provided with a riband recess to prevent independent movement, and the expander seatedbetween the blocks for hold ing the section expanded; substantially asdescribed.
